What are the advantages of using an assembly programming language in comparison to using an Object Oriented programming language?

Answer 1

The main strength is that it gives complete control over the machine at the lowest possible level. The main weakness is that everything must be encoded in terms the machine can understand. For instance, the otherwise simple operation of x = y + z requires that we move the values stored at the addresses identified by y and z into the appropriate CPU user registers, then invoke the appropriate ADD instruction, then move the accumulator register value into the address identified by x. That's a lot of work for an otherwise simple operation.

Answer 2

An assembly language has faster execution than its object-oriented counterparts. Also, there is no need for compilation, just linking (assembly languages were the precursors to compilers).

Assembly language is low level English better suited to continuously running the same small process over and over again. It only has a small alphabet and is, hypothetically, easier to manage than OOP. Is high level English and Compiles introduces uncertainty about the time cost of operations. In Assembly one has tight control over the instructions that are executed. Reducing the size of program means fewer memory chips are needed, reducing cost.

Answer 3

Extremely low-level symbolic language. The only thing lower than assembly is machine code, where all code is written in binary (typically using a hex editor). Assembly lifts the level of abstraction beyond hexadecimal, replacing machine operation codes (opcodes) and CPU registers with easy-to-remember mnemonics, usually 3 or 4 characters in length (such as MOV for a move operation, and ADD or SUB for arithmetic addition and subtraction). Operands (whether memory addresses or literal values) can be notated using decimal, hexadecimal, octal or binary notation.

Translation from assembly to machine code can be easily implemented in software. For example, the MOV operation typically has at least three variants: moving a value from main memory to a register, from one register to another register, and from a register back to main memory. The translator simply refers to the operand types to determine which specific binary opcode to generate.

Assembly and disassembly are very closely related. Disassembly is essentially the assembly language interpretation of machine code (a type of reverse engineering). However, assemblers don't read user-comments (comments exist purely to assist the code maintainer, not the machine) and variable names are replaced with memory offsets. Thus the resulting disassembly can be difficult for a human to interpret properly without access to the assembly source. However, if you have the source, you don't need to disassemble the machine code.

Answer 4

Assembly is slow and complex to write, but extremely quick to execute.
